The Heat Pump Retrofit Best Practices Guide for Contractors (V2) aims to help contractors deliver high-quality, efficient, and homeowner-focused heat pump retrofits. The content reflects current standards, emerging best practices, and the realities of retrofit work in British Columbia homes. The user-friendly guide provides contractors with clear, actionable direction for performing heat pump retrofits using a planned approach organized around these five core steps:
- Pre-Changeout Procedures
- System Design (sizing and selection)
- Installation
- Commissioning
- Homeowner Education and Maintenance
The guide also incorporates highly relevant graphics and provides additional resources to support successful projects that advance industry standards. These visual elements help clarify concepts and improve accessibility. The supplementary resources identified in the guide further enable contractors to apply the guidance consistently and effectively, supporting higher-quality outcomes and knowledge transfer across future projects.
RDH developed this guide for the nonprofit Home Performance Stakeholder Council (HPSC) to serve as both a standalone document and a companion guide to HPSC’s contractor training program, “Quality Installation of Forced Air Furnace and Air Source Heat Pump Retrofits in BC Homes.”
